What is the difference between decomposing aluminum and aluminum dioxide?
The decomposition reaction of aluminum usually did not occur under conventional conditions because aluminum was a simple metal and was relatively stable. If aluminum was produced from aluminum compounds, the industrial production method was to produce aluminum by smelting molten aluminum dioxide (Al2O2). The reaction equation was: 2Al2O2 == 4Al3O2 (The conditions were that electricity was supplied, the aluminum dioxide was molten, and the flux was cryolite). Aluminia (Al2O2) is an amphoric oxide. Its decomposition reaction is mainly to decompose into aluminum and oxygen when it is energized and in a molten state. Therefore, aluminum itself generally does not undergo a decomposition reaction (special nuclear reactions are not taken into account), and the decomposition reaction of aluminum dioxide is to decompose into aluminum and oxygen in a molten state.

Why doesn't aluminum react with hydrogen ions in the reaction between aluminum and iron chlorideiron?
In the reaction system of aluminum and iron chloride-aluminum, the aluminum would actually react with the hydrogen ions produced by the decomposition of iron chloride-aluminum. Ferric acid was then digested to produce hydrogen ions, and aluminum reacted with the hydrogen ions to produce hydrogen gas. Therefore, when aluminum reacted with FeCl3, it would react with hydrogen ions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The aluminum reacted to form a hydrogen solution
The solution that reacted with aluminum to produce hydrogen was an acidic or strongly basic solution. There were large amounts of hydrogen ions in acidic solutions, and large amounts of hydrogen ions in strongly basic solutions. For example, the reaction of aluminum with sulfuric acid can produce aluminum chlorideand hydrogen gas, and the reaction of aluminum with a solution of soda ash can produce aluminum metaaluminum and hydrogen gas. When considering the co-existence of ions in the solution, some ion combinations in the solution that reacted with aluminum to form hydrogen could not coexist in large quantities. For example, under acidic conditions, iron ions and nitrates would undergo an oxidoreduction reaction, and iron ions would react with hydrogen ions, so solutions containing iron ions and nitrates could not react with aluminum to produce hydrogen. The combination of the two types of ions could not coexist in large quantities in a solution that reacted with aluminum to form hydrogen. For example, Al3 +, Mag2 +, SO42-, and Na+ did not react with each other and did not react with hydrogen ions. They could coexist in large quantities in acidic solutions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of aluminum and hydrogen and oxygen
When there was a small amount of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++3OH - =Al(OH)3; when there was an excess of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++4OH - = AlO2-+2H2O. When a small amount of oh-ions gradually becomes excessive, the chemical equation of the reaction between aluminum ions and oh ions is: AI (OH)3+OH - = AlO2-+2H2O. The ion equation for the reaction of aluminum with water is: 20H- +2Al+2H2O→ 2AlO2-+3H2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Magnesium-aluminum and oxygen reaction experiment
The following is related to the experiment of the reaction between magnesium-aluminum and oxygen: ** 1. Reaction between Magnesium and oxygen ** 1. ** Reaction Phenomenon ** - When it burned in the air, it would release heat and emit a dazzling white light, forming a white solid. - The reaction was more intense in oxygen than in air. 2. ** chemical equation **:<2MG + O_{2}><stacking>{=<<=<<=>>>=<>>2MgO\) 3. ** Points to note in the experiment ** - Due to the intense combustion of the titanium, safety must be paid attention to during the experiment and a certain safe distance must be maintained from the titanium. - When burning, it will produce a strong light, which may cause damage to the eyes, so don't look directly at the burning magnetite. ** 2. Reaction between aluminum and oxygen ** 1. ** Reaction Phenomenon ** - When aluminum reacted with oxygen in the air, a layer of dense aluminum dioxide film would be formed on the surface of the aluminum. This film would prevent the aluminum from being further oxided, so the reaction between aluminum and oxygen in the air was not so intense. The surface of the aluminum gradually lost its metallic luster. - If the aluminum foil was heated in oxygen, the aluminum foil would melt, but it would not drip. This was because the melting point of the aluminum dioxide film was very high, and it would hold the molten aluminum and emit a dazzling light during the reaction. 2. ** chemical equation **:<4AI +3O_{2} = 2AI_{2}O_{3}> 3. ** Points to note in the experiment ** - When conducting the experiment of heating the aluminum foil in oxygen, the purity and sufficient supply of oxygen must be ensured. - When heating the aluminum foil, use a suitable heating tool, such as an alcohol lamp, and heat it evenly. ** 3. Experimental design (Comparing the reactions of oxygen with aluminum and aluminum)** 1. ** Experiment Purpose ** - Comparing the intensity of the reaction between aluminum and oxygen, the reaction products, and so on. 2. ** Experiment Steps ** - He took a suitable amount of aluminum foil and a suitable amount of aluminum strip, and polished them to make them bright (to remove the thin film of oxygen on the surface). - Heat the aluminum foil and the aluminum strip separately over the flame of an alcohol lamp (or ignite them in a gas collector filled with oxygen). - Observe and record the intensity of the reaction between the two (such as the reaction of the aluminum strip is more intense, emitting a dazzling white light; the surface of the aluminum foil gradually changes when heated, and it will also emit light when ignited in oxygen, etc.), and the phenomenon during the reaction (such as the combustion of the aluminum strip to form a white solid, the formation of a white aluminum dioxide film on the surface of the aluminum foil, etc.). - After the reaction, the reaction product was analyzed (it could be judged by physical properties such as color and state, or it could be further analyzed by chemical methods). 3. ** Experiment result analysis ** - Based on the intensity of the reaction, it could be judged that the reaction between oxygen and titanium was easier than that of aluminum. - Through the analysis of the reaction products, it could be determined that the reaction between the oxygen and the aluminum formed the aluminum dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
